Melanie Stryde has turned 17. That means she is eligible for Selection. This is the ceremony in which young adults are sent away to the Dome, a facility in which you learn Control approved things. She lives in Orbis. A place created for balance and peace. Earth has been separated into seven tracts, and Mel lives in the seventh tract with her family of two sisters, a brother, and her two parents. Once turning 17, you are subject to a training facility where you will learn things. What things exactly, she is unsure of. So going into this, Melanie doesn't know what to expect. No one who returns from the Dome is permitted to give any information out as to what they do. So everyone younger than 17 is clueless. Every 17 year old is obligated to enter, and if they don't, they are banished from the tracts, and sent to live in the outside world, where the attacks and bombings occurred during the war. So people obey. Mel thinks you are sent there to only learn something boring. Something she'll never actually need to know in later life. Although she is soon proven wrong when she arrives at the Dome, and is instructed to do something that never crossed her mind. As Mel struggles to adjust to this new environment, she learns life lessons, and things about herself she never knew existed.
